U-joint vs pot coupler
Hey Dave 99 ,
Very easy to see where the pot coupling can be of use. The flex in the factory K Member is very noticible. Covered by Firm Feel and also by Mopar Action Magazine I believe. Firm Feel actually modifies K-Members to reduce or eliminate flex. I'm guessing the pot coupler can help compensate for the flex transmitted back through the steering column but will wear out doing so.
